Abstract
The cartridge (11) for an inked ribbon (41) comprises a casing (12) having a magazine (42) for housing the ribbon (41) of the closed loop type and disposed in randomly distributed turns, and a pair of rollers (52) for the feed movement of the ribbon (41). A re-inking pad (58) is rotatable in the casing (12) and an ink distribution roller (48) co- operates with the pad (58) for re-inking the ribbon (41). The distribution roller (48) comprises a shaft (53) having its ends projecting from the ends of the roller (48) and housed for rotary and sliding movement in slots (56) and (54) in the casing (12) and the cover (22). The slots (54) and (56) are rectilinear and have their axes co-planar with the shaft (57) of the pad (58) to permit movement of the roller (48) away from and towards the pad (58). The distribution roller (48) is held in contact against the pad (58) by the tension applied to the ribbon (41) by the rollers (52). The tension of the ribbon (41) automatically regulates the contact pressure of the distribution roller (48) against the re-inking pad (58) and optimises re-inking of the ribbon (41).
Description
- The present invention relates to a cartridge for an inked ribbon with a re-inking pad, comprising a casing having a magazine for housing the inked ribbon of closed loop type and disposed in randomly distributed loops, and a pair of rollers for the feed movement of the ribbon. The re-inking pad is rotatable in the casing and an ink distribution roller co-operates with the pad for re-inking the ribbon.
- Various cartridges of that type are known. In a first type of cartridge, the pad is rotatable on a fixed pin and the distribution roller is mounted on an eccentric which can be manually adjusted for increasing or reducing the contact pressure of the roller against the pad. In a second type of cartridge the distribution roller is rotatable on a fixed pin while the pad is rotatable on a pin of an oscillating frame structure which is held in contact with the roller by means of a spring. In a third type of cartridge, the pad is rotatable on a fixed pin while the distribution roller is mounted in an oscillating frame structure or bridge member which in turn is held in contact against the pad by the tension of the ribbon which is due to the feed movement thereof. All those constructions are complicated and thus relatively expensive.
- The object of the present invention is-to provide a cartridge for an inked ribbon with inker which is reliable, simple and which at the same time is functional, practical and inexpensive.
- To this end the cartridge according to the invention is characterised in the manner set forth in
claim 1. - A preferred embodiment of the present model is represented by the following description which is given by way of non-limiting example and with reference to the accompanying drawing which shows a plan view of part of the cartridge for an inked ribbon with re-inking pad according to the model.
- Referring to the drawing, the cartridge is generally indicated by
reference numeral 11 and comprises acasing 12 of a substantially parallelepipedic shape with connected rounded corners. Thecasing 12 comprises abottom 13 and a series ofwalls cavity 21. Thecasing 12 is closed upwardly by acover 22, afront wall 23, arear wall 24, a right-hand side wall 26 and a left-hand side wall 27. Eachside wall seat resilient element carrier 33 of aprinter 34 for positioning thecartridge 11 when it is supported with itsbottom 13 on thecarrier 33. - The
cartridge 11 comprises two suitably shapedarms hand side wall 26 and therear wall 24 and which have twoopenings ribbon 41 to be passed and guided in front of a per se knownprint head 35. The inkedribbon 41 is of the closed loop type and is disposed in randomly distributed turns in amagazine 42 of thecasing 12. Theribbon 41 issues frcm themagazine 42 and is pinched between afixed guide 43 and aresilient blade member 44 which permits more turns from coming out of the magazine, the guide and the blade member tensioning theribbon 41 in front of thehead 35. Theribbon 41 then passes through theopening 39, coming out of thecasing 12, to take up a position in use in front of thehead 31, re-enters through theopening 38 and, after having been guided byfixed guides ink distribution roller 48. Subsequently, guided byfixed guides ribbon 41 is engaged with a pair of rollers generally identified byreference numeral 52 for the unidirectional feed movement thereof, and it is then passed again into themagazine 42. - The forward feed movement of the
ribbon 41 is effected by one of the tworollers 52 being driven by theprinter 34 in per se known manner. - The
distribution roller 48 is formed by a cylinder whose side surface constitutes the active part with ashaft 53 having the two ends thereof projecting from the cylinder and being capable of being housed in a slot orgroove 54 in thecover 22 and in a slot orgroove 56 in thebottom 13. Theslots shaft 57 of are-inking pad 58. - The
re-inking pad 58 is rotatable with itsshaft 57 within thecasing 12 while thedistribution roller 48 is also rotatable within thecasing 12 but can slide in theslots shaft 57. - The inked
ribbon 41 engages thedistribution roller 48 as described hereinbefore and, by virtue of the effect of the tension applied by therollers 52, causes thedistribution roller 48 to slide along theslots re-inking pad 58. During the feed movement of theribbon 41, the tension of theribbon 41 causes rotary movement of theroller 48. - The active part thereof which is in contact with the
pad 58 causes ink to be transferred from thepad 58 to theribbon 41. In addition the tension of theribbon 41 is such as automatically to regulate the contact pressure between thedistribution roller 48 and there-inking pad 58 and optimises re-inking of theribbon 41. - It will be apparent therefore that the
distribution roller 48 is rotatable and slidable in theslots ribbon 41 holds theroller 48 in contact with there-inking pad 58 and causes rotary movement thereof, providing for automatic regulation of the contact pressure of theroller 48 with thepad 58 and optimising the re-inking effect for theribbon 41.
